如果列表具有相同的值，则使用zip将两个列表组合为键值对 [英] Combine two list as key value pair using zip if lists have same values

问题描述

我有两个列表:

yy = ['Inside the area', 'Inside the area', 'Inside the area', 'Inside the area', 'Inside the area', 'Inside the area', 'Outside the area']
lat_ = [77.2167, 77.25, 77.2167, 77.2167, 77.2, 77.2167, 77.2]

我正在使用以下文章中给出的解决方案来组合它们:

I am combining them using the solution given on some posts here by:

new_dict = {k: v for k, v in zip(yy, lat_)}
print new_dict

但是我的输出是 {区域内":77.2167，区域外":77.2}

之所以会这样，是因为大多数键是相同的.之所以这样做，是因为我想映射这两个列表，以便获得哪些lat值位于内部或外部，然后仅保留那些位于内部的值.

This is happening because the most of the keys are same. I am doing this because I want to map these two list in order to get which values of lat falls inside or outside, and then keep only the ones which fall inside.

推荐答案

您可以压缩它们并在列表理解中添加防护:

You can zip them and add a guard inside a list comprehension:

res = [lat for a, lat in zip(yy, lat_) if a.startswith("Inside")]
